Engineers with cold lubricant making us spring back (6)
I believe the answer is:
recoil
'spring back' is the definition.
(I've seen this before)
'engineers with cold lubricant' is the wordplay.
'engineers' becomes 're' (abbreviation for Royal Engineers).
'with' means one lot of letters go next to another.
'cold' becomes 'c' (eg on taps).
'lubricant' becomes 'oil' (I've seen this before).
're'+'c'+'oil'='RECOIL'
'making us' acts as a link.
(Other definitions for recoil that I've seen before include "Spring back; flinch" , "(As a firearm) spring back" , "Spring back in horror" , "Flinch or start back (6)." , "backlash" .)
